I need to write some code to get a polygon (list of lat/lng points) that surrounds a number of lat/lng points on a map.
This polygon needs to surround the points tightly, so a simple rectangle (which would be very easy to code) won't do.
This link looks promising: https://github.com/mapbox/concaveman
And I wonder if maybe somebody of this group has already coded this for B4A.
In that case I would be very interested to see that code.
Didn't think it would be a problem but have tested now for the positive to negative longitude change we do have in the UK and that is indeed fine.
Will test now for your mentioned wraparounds.
